WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,158, dated May 6,1890.

Application filed October 19, 1889. $erial No. 327,486. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM F. COOPER, a citizen of the United States,residing at Dubuque, in the county of Dubuque and State of Iowa, haveinvented certain new and useful Improvements in Wood-\Vorking Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the'same, reference being hadto the accompanying drawings,'and to letters of reference markedthereon, which form a part of this specification.

This invention pertains to certain new and useful improvements inwood-working machines, having reference more particularly to such as areused for tenoning and chamfering pieces of frame-work, and especiallyapplicable in the manufacture of spokes and like articles.

The invention consists, briefly, of a frame having an adjustable orsliding carriage for carrying the piece of wood and a series ofcoaxially-arranged adjustable saws and disks or wheels carrying knivesand cutting-tools, whereby the operation is completed in the passage ofsaid carriage from one end of its movement to the other,substantially ashereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of myimproved ma- Fig. 2 is a detail view of a portion of the carriage,showing a piece of wood as presented to the truing-knives. Fig. 3 is aview showing the tenoning or chamfering disks or wheels and apiece ofwood after being acted upon by the latter. Fig. 4 is a view of both suchwheels. Fig. 5 is a detail perspective view of the wheel and knives forbacking and beveling the tenon.

Referring to the drawings, A designates the main or stationary frame,constructed after any preferred form, and aa sliding or movable carriagehaving at one end a grooved bar a, running on a vertically-adjustableguide a and at the other end a roller a resting on the upper edge of anadjustable board a of frame a. To carriage A are secured adjustablesupports B, upon which the piece of wood is appropriately secured.

O is a shaft resting in suitable journalboxes, and provided at one endwith a disk or wheel D, having cutting-knives d, for truing, facing, orstraightening the end of the piece of wood to be tenoned, and near theother end of this shaft is a second disk or wheel E, having a conveXedface, and provided with knives e e, for backing or beveling the tenon.

F is a second shaft at right angles to shaft 0, and upon it are securedcircular saws G G, capable of adjustment longitudinally of the shaft byany ordinary means, so as to secure the length desired for the piece ofwood.

H H are two upper and lower disks or wheels secured upon short shafts h,preferably adjustable horizontally by having their ends secured independing plates provided with corresponding holes or apertures, asshown at H Fig. 1. These disks or wheels are provided with alternatingseries of sawteeth h h, chamfering-teeth h 71 and planing-knivesh it forthe purpose of finishing the-tenon end to the proper requirements. Itwill be seen that the teeth and knives of these disks or wheels arecorrespondingly arranged, so that they will act conjointly upon thepiece of wood undergoing operation.

Upon shafts h h are secured band-pulleys -i 2', around which is passed acrossed belt 2'', so that disks H H move in the same direction, and uponthe shaft of the lower disk or wheel is a second pulley 2' with whichengages a belt I, passed over an upper pulley 11 and a lower wheel J ona shaft j. A second wheel j is also secured on this shaft, and motion isI imparted from a driving-belt f passed therearound. Further power isobtained through belts K K K said belts K and K being passed,respectively, around pulleys 70 70' on shafts C and F, whereby motion isimparted thereto.

The operation of my invention is as follows: The piece of wood to beoperated upon is first secured upon supports B of carriage a, which isthen at its starting-point m, Fig. 1. The carriage is moved by the handof the operator,

and the end to be tenoned is first subjected to the action of the'knivesof disk or wheel D for truing thereof, and after this is accomplishedfurther movement of the carriage presents both ends of the piece of woodto the action of the circular saws G, whereby the same is reduced to theproper length. The next operation is that effected by the disks orwheels II II, whereby the end of the piece of wood is tenoned andchamfered by the action of the saw-teeth, chamfering-teeth, and theplaning-knives. The final step of the operation is effected by thepresentation of the tenoned end to the action of the knives of the diskor wheel E, whereby the backing or beveling of the tenon isaccomplished, and the carriage has then reached the limit of its movement, after which it is returned to its starting-point for furtheroperation. Thus it will be seen that the entire process or operation oftruing, sawing, tenoning, chamfering, and backing of a piece of wood isaccomplished in the single passage of the carriage from one end of itsmovement to the other. It will also be observed that by rendering thecircular saws adjustable on their shaft and making ad justablehorizontally the shafts of the disks or wheels 11 II the piece of woodor spoke can be reduced to any" desired length and the tenons andchamfers formed therein at different de grees.

I claim as my invention.

1. In a wood-working machine, the combination, with the sliding framefor carrying a piece of wood, of a disk or wheel having knives fort-ruing one end of such piece of wood, parallel saws for sawing the endsthereof, two disks or wheels for simultaneously tenoning and chamferingsaid end of such piece of wood, and a disk or wheel having knives forbacking said end, substantially as set forth.

2. In a wood-working machine, the combination, with the sliding framefor carrying a piece of wood, of a disk or wheel having knives fortruing one end of such piece of wood, parallel rotary saws, togetherwith their shaft, upon which they are adjustable, two disks or wheelsfor tenoning and chamfering said end of said piece of wood and havingtheir shafts adjustable in bearings, and a disk or wheel having knivesfor backin g said end, substantially as set forth.

3. In a wood-working machine, the combination of the shaft 0, havingdisks or wheels at or nearits opposite ends provided withcutting-knives, the parallel saws arranged adjacent to one of said disksor wheels, the disks or wheels for chamfering a piece of wood locatedbetween said saws and the other disk or wheel on shaft C, and thesliding frame having supports for such piece of wood, substantially asset forth.

l. In a wood-working machine, the combination of the disks or wheels DE, having cutting-knives and located at opposite ends of thesupporting-frames, the parallel circular saws adjacent to said disk orwheel D, and the upper and lower disks or wheels having saw andchamfering teeth and planing-knives and located between said saws andthe disk or wheel E and the sliding carriage, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
